Human Nervous System

Human nervous system tries to minimize the effect of any external perturbing force by bringing modifications in the internal model. These modifications affect the subsequent motor commands generated by the nervous system. Adaptive compensation along with the appropriate modifications of internal model helps in reducing human movement errors. In the current study, we studied how motor imagery influences trial-to-trial learning in a robot-based adaptation task. Two groups of subjects performed reaching movements with or without motor imagery in a velocity-dependent force field. The results show that reaching movements performed with motor imagery have relatively a more focused generalization pattern and a higher learning rate in training direction.

The current study tested the timing element of the PETTLEP approach to motor imagery (Holmes & Collins, 2001) by examining the effects of 3 imagery conditions on the performance of a soccer dribbling task. The imagery conditions were also compared with physical-practice and control-group performance. Ninety-seven participants were randomly assigned to 1 of 5 conditions: real-time imagery, slow-motion imagery, slow motion concluded with real-time imagery, physical practice, or control. Results indicated that all 4 experimental groups significantly improved time and error performance to the same degree after the intervention. The control group significantly improved time but not error performance from pre- to post-intervention. The results of the current study provide inconclusive findings related to the timing element of the PETTLEP approach to motor imagery, however, and do suggest that slow motion might be a viable imagery characteristic. Limitations regarding the examination of slow-motion imagery, possible implications of its use, and suggestions for future image-speed research are discussed.

Over the past 2 decades, much work has been carried out on the use of mental practice through motor imagery for optimizing the retraining of motor function in people with physical disabilities. Although much of the clinical work with mental practice has focused on the retraining of upper-extremity tasks, this article reviews the evidence supporting the potential of motor imagery for retraining gait and tasks involving coordinated lower-limb and body movements. First, motor imagery and mental practice are defined, and evidence from physiological and behavioral studies in healthy individuals supporting the capacity to imagine walking activities through motor imagery is examined. Then the effects of stroke, spinal cord injury, lower-limb amputation, and immobilization on motor imagery ability are discussed. Evidence of brain reorganization in healthy individuals following motor imagery training of dancing and of a foot movement sequence is reviewed, and the effects of mental practice on gait and other tasks involving coordinated lower-limb and body movements in people with stroke and in people with Parkinson disease are examined. Lastly, questions pertaining to clinical assessment of motor imagery ability and training strategies are discussed.
